The same letters refer to the same or corre-' sponding parts throughout the several views.

AArepresent the sides of the machine; A the top, the top and sides paneled. The front end of the machine is provided with a hinged frame, 0, on which is secured the platform or foot-board O The frame 0 is hinged at (J to the lower front part of the sides A A in such manner as to fold up or down, as shown in Figs. 1, 2, and 4.

Above the 'ilatform-frame G is another frame, 0 which has a hinged teed-table, C

on top. This frame also is hinged to the sides A A by the pivot-bolts C, as shown in Figs. 1 and 2. -The outer ends of the lower frame, 0, and the upper-feed-table frame, G are united together by the links 0 C The rear end of the upperfeed-table frame, rests against the ends of the sides A A when the frame is folded down, as shown in Fig. 1. When in this position the link 0 the upper end of which is provided with a hook, is hooked into the eyebolt (J7, and thus the lower frame, 0, is supported in a horizontal position, as shown in Fig. 1. When it is desired to fold the frames 0 and 0 up the link (3 is unhooked from the eyebolt (J and the frames tilted up. The link (J is then hooked into the eyebolts G in the sides A A, as shown in Fig. 2.

The feed-table G is hinged or pivoted to the sides of the frame 0 and when saidframe is elevated, as in Fig. 2, the feed-table is folded up against the front end of the machine, thus elosing up part of the end of the case, as shown by dotted lines in Fig. 2.

The cylinder G, which is of the ordinary patv tern, is provided at each end with a band, G which bands are secured firmly to the bars G". The inner edge of each band G is provided with a corrugated flange, G These flanges G divide the cylinder into three partsi. 0., the middle part between the flanges for thrashing off the straw and the outer partsbetween the flanges and sides A A of the machine for treating the tailings, as will be hereinafter described. The oylinder G is mounted on the shaft R and the sh'aftis mounted in the bearings d of the bracket d and d of the bracket 1 These brackets are shown in detail in Figs. 9 and 1t).

The upper end of thebraeket (1 projects sidewise from the side A of the machine far enough to permit the pulley F to revolve freely in the space, as shown in Figs. 5 and 8. These brackets d and o are securely bolted to the sides A A of the machine, and their lower ends are firmly bolted to the concave floor brackets G. These concave floor brackets G6 are also secured to the sides A A and frametimbers A A, and each bracket is provided with a curved groove, 9, for receivingand holding the tloor G as shown in Figs. 6, 7, S, and 4. Below the concave floor l and between it and the bolsterplate A, is a heavy piece of timber, A the ends of which are firmly sccured to the lower ends of the brackets (l and 'v and sides A A of the machine, and thus form a strong supporting-frame for the cylinder G and prevent the cylinder-shaft 11 from getting out of line withits boxes.

The cylinder-shaft R is provided with a bevcl-pinion, R, which is keyed fast to the shaft a short distance inside of the end of the cylinder, as shown in Fig. 5. The bevel-wheel R works in gear with the pinion It. The wheel R is mounted on the shaft D, and said shaft is mounted in the boxes I) D which are secured to the side of the machine, as shown in Fig. 1. The wheel 1% is also incased in the cover D, as shown in Figs. 1 and 5.

A short distance in the rear of the c linder G the fan I) is located, as shown in Fig. 4. The fan-case D Figs. 15 and 16, is closed all around, except at the rear side, which is open and provided with a series of adjustable slats, 0'. The ends of these slats r are journaled in the castings D b and D], with knobs r at one end for the purpose of turning the slats into any desired position. In Fig. 18 the left-hand side of the slats are represented as closed, while the right-hand side shows the slats open to permit air to pass through the spaces i, Fig. 4, underneath the shaking-screens Ir 7; It" It.

The upper front part of the shoe K and the floor in front of the screen It passes over the fan to a point in front ofthe center ofthe fan, and the front ends of the screens and 7." of said shoe stopin frontof the fan opposite the slatsr. The front end of the shoe K is beveled underneath and operates over the horizontal projection H of the floor 11 of the grain-carrier belt II, as shown in Fig. 2. The rear end of the shoe K is secured to the spring-hangers M, so as to allow the shoe to vibrate forward and backward.

Below the shoe K is another shoe, K, having two screens, b above and it below. The front ends of both screen-shoes K and K are pivoted on a rocker-bar, M which bar has a pivot-stud extending through the side ofthe machine, with a crank, E, outside, which is operated by the rod E and crank-wheel 1 The rear end ofthe lower shoe, K, is supported in the spring-hangers M, as shown in Fig. 4.

The rear ends of the screens 7: k discharge any straw and chaff that may pass over them onto the stacker 0, and the rear ends of the lower screens, k 7.1, do not project so far as those of the screens above, and are each provided with springs near the ends, with inclined return-boards It 70 below, for the purpose of preventing grain from going over the ends of the screens, and to conduct the grain which passes through the openings into the spout 0 below. The spout O and its discharge.- pipe 0 are made fast to the lower shoe, K. The lower end of the pipe 0 discharges the grain which passes through it into the cross shaking-spout 0.

Above the spout 0 is another spout O",likewise a crossspout, designed to catch any grain which may fall from the stacker or pass over the ends of the screens It L k it. These two cross shaking spouts are secured together by the pivoted rockerbars P l" at each end. These rocker-bars are'made fast to the square shafts l, which shafts operate in suitable bearings, 1 at one end and, P at the. other end.

The shafts l, the rocker-bars I?" P, and the spouts 0 O are operated by the spout 0, through the medium of the rod 3 arm y, vertical rocker-shaft Q, arm 3 and link 1 as shown in Fig. 13. Thus one end of the rod 3 is made fast to the spout O, the other end of the rod if is pivoted to the arm of ofthe vertical rocker Q, the upper and lower ends of said rocker (Q. are pivoted in the brackets t 1, Fig. 4. The arm got" the rocker Q, is pivoted to the link 1 and the link 9 is pivoted to the side plate, 3 of the cross shaking-spout 0 Thus when the pipe 0 moves in thedirection of the arrow 3 Fig. 13, the spout O is moved at right angles thereto in the direction of the arrow 9 which motion is reversed as the pipe 0 moves in the opposite direction. As the spout moves in either direction the lower spout, moves in an opposite direction by reason of the rocker-bars 1" l.

The grain-carrier belt H is of the ordinary construction of the slat pattern, and passes around a bar, 12, below the bottom of the floor 11, close to the lower rear side of the cylinder G. The belt H receives its motion from the spur-wheel a on the shatt of the wheel F, and the belt is of the same width as the space between the corrugated flanges G of the cylinder Gr.

The upper inclined floor, H, of the grainca-rrier belt H extends from the barn to a point above the side conveyer-boxes, c, and above that point, as far as the spur-wheel a, the iloor H is provided with a series of slats, 11 having vertical openings between them to permit any loose grain carried up by the belt H to drop through said openings and through the spaces between the slats-of the belt on the lower side onto the front end of the screen k of the shoe K. The lower inclined tloor, H

steam 3 of the belt II is connected with the concave tloor G3 of the cylinder G by the curved part Hiand the upper end of the floor H is provided with the horizontal part H which pro- 5 jects backward under the beveled end of the shoe K above the fan. The rear side of the concave tioor G of the cylinder is provided with a series of rearwardly-projecting inclined fingers or prongs,f for the purpose of guiding the straw onto the belt H.

Above the discharge-opening ot the cylinder is a cross-bar,f to the lower end of which, at f, is hinged the deflector f, which is of the ordinary kind. The front end of the strawcarrier belt H is mounted on the spur-wheel driver H with the roller H below. The lower side of the belt H slides on the tioor H; At the rear end the belt H passes around the spur-wheel H The upper side of the belt is supported by the two beaters H H", as shown in Fig. 4. The spur-wheels H, at the rear end of the belt 11, are mounted on the outer ends of the arms N, and the inner ends of said arms are pivoted to the brackets N, for the purpose of allowing the rear end of the belt H" to be folded up, as shown in dotted lines in Fig. 4, where the lower section, (J, of the stacker is folded inside of the end of the machine.

Above the front end of the belt H, and 0p erated by the shaft a, is a straw-pitching mechanism consisting of the shaft a, to which, at each end, on the inside of the casing A A, is secured the arms W. The lower ends of these arms are pivoted to the fork-shaft I. The fork-shaft has inclined tingers or prongs, 1, projecting backward, and at each end of the shaft I are the inclined arms m. The upper ends of these arms at are pivoted to the upper ends of the links on, and the lower ends of the links m are pivoted to the sides A of the machine. The shat't a extends through the side of the machine, and one end is provided with the crank E, and the whole pitching apparatus is operated by rod E, which is connected with the crank E of the shaft a and the crankwheel E on the end of the beater-shaft E The pivot-stud of the bar M of the shoes K K extends through the side of the machine, and is provided with a crank, E This crank is connected with the crank-wheel E of the beater-shaft E and when the machine is in operation causes the shoes K K to vibrate longitudinally, the upper shoe, K, moving back while the lower shoe, K, moves forward, and vice versa.

The straw-stacker (J is made of two sections. The lower one is pivoted to the sides A A at 1) and the lower section, 0, is short enough to fold inside of the end of the machine, and is supported when down by the side chains, 0. The outer section, 0 of the stacker is raised and lowered by the rope A which has one end attached at or near the outer end of the stacker, and the other end is made fast to the Windlass-shaft e in the boxes A above the machine. The outer section of the stacker is raised grad uallyas the height of the stack increases, without raising the section 0; but when the hinged ends of the sections 0 and 0 are brought together, then both sections may be raised at the same time.

The beater E is of the ordinary kind, and is mounted on the shaft E said shaft having on one of its outer ends the pulley F, and on the other end the crank-wheel E, and on the inside of the case A, at each end of the beater, the'shal't' is provided with spur-wheels J (Shown more fully in Fig. 14.) The wheel J has spurs s to engage with the links of the chain J, and is further provided with notches s for the [lights j of the conveyor-chain to enter. The upper end of the conveyer-chain J operates on the spur wheel J, and every third flatlink of the chain is provided with a thin flat iron tlight,j. (Shown fullyin Figs. 13 and 14.) The lower side of the chain J operates in the inclined conveyor-boxes c at the sides of the machine inside from the lower rear end of the machine. to the front upper end. The upper part of the chain J, after leaving the spur-wheel J, passes nnderthe wheel J of the beater E, and over the roller J", thence diagonally downward over the roller J thence to the lower rear corner of the machine, where it passes over the spur-wheel J, as shown in Fig. 4. These conveyer-chains are used for conveying the tailings to the front of themechine and discharging them through the spouts 6 onto the cylinder G, between the corrugated flanges G2 and sides of the machine-case,w here the tailings receive a second treatment, and are then thrown by the cy linder onto the graincarrier belt at the sides of the straw to be reelevated.

On the outside of the machine (Fig. 2) is shown the arrangement of pulleys for operating the machine. The pulley F operates the beater E". The pulley F operates the spurwheel a of the grain-carrier belt H. Thepnlley F operates the straw-stacker belts, as shown in dotted lines in Fig. 4. The pulley F operates the fan. The pulley F is the cylinder-pulley from which power is furnished to run all the rest of the machine. The pulleys F F are tightener-pnlleys, arranged on the bar F This baris pivoted to the machine at b, and its upper arm operates in the rack F and has a handle, I), at its upper end.

The main belt F passes over the cylinderpulleyF, underthefan-pulley F and part way around it, thence around the pulley F and partly around the butter-pulley F, thence with a twist around the straw-stacker pulley F, thence over and under the tightener-pulleys F F,thencebaek tothecylinder-pulleyF Thus the one belt operates the entire machine except the cylinder.

()n theopposite side ofthemachine, as shown in Fig. l, the upper grain-carrier belt-shaft is provided with a belt-wheel, B and the front shaft of the straw-carrier belt is also provided with a corresponding belt-wheel, 13'. Power is ICO IIO

communicated from belt-wheel B to the wheel 13* by the chain B and the chain B and both wheels 13 B are inclosed in the box B The grain-elevating apparatus is partially shown in Fig. 11, Sheet 4.

The rear end of the machine, at each side of the bottom, is provided with elevator'boots O 0*, into which the grain is discharged from the spout 0 The boot 0*, Fig. 11, is provided with an elevatorleg, 0, which has its lower end hinged at 0 to the side of the machine.

In operating my improved machine power is applied to the shaft I) from any ordinary horse a power. The bevel-wheel It operates the wheel It and rotates the cylinder G, the main belt F operating all other parts of the machine, as before described. The grain to be thrashed is fed to the cylinder from the feed-table C, and the straw thrashed off by the central part of the cylinder between the flanges G The thrashed grain and straw are then elevated by the grain-belt Hand the grain falls through between the slats II, and that which passes over the upper end of the carrier is deposited on the upper screen,k, of the shoe K, for separation from the chaff and line straw. The elevated straw passes onto the straw-carrier H and is conveyed to the rear end of the machine and deposited on the stacker. While the straw is passing out of the machine the pitching device above the carrier belt H is operated-that is, the forks I on their backstroke are moved backward and upward, thus pitching the straw and releasing any grainheld thereby,as shown bydotted linesin Fig. 4. On the forward stroke ofthe pitcher the forks I are moveddownward and forward in the position, also shown in Fig.4, ready to again move backward and upward and pitch more straw. The grain which falls on the screen falls through onto the liner screen It below, where it receives a currentof air from the fan through the space i at the topbetween the upper slat, r, and front iloor of t he screen It. This current of airblows away the chalf and the grain is shaken along the oat riddle or screen k, and the grain is deposited onto the wheat riddle or screen k of the shoe K below. Here the wheat again passes through a current of air through the space '1' between the top slat and the slat below it, and as the grain is sifted through the wheat riddle k it falls onto the seed riddle or screen k. Here itagain encounters anothercurrent of air-from the fa 11 through the corresponding space i between the slats, and as the seedscreen it is very fine no wheat passes through it, but is shaken along to the rear end, where it falls into the spout O and through the pipe 0 into the cross-spout 0 Here the grain is conducted into the boot of the elevator and measuringdevice,elevated, and measured. Any light stufl, chatl', or tailings which may pass over the ends of the screens k I.: k falls into the cross-spout 0", and is conducted to the base of the machine into the lower end of the conveyer-box c. The chain Jeonveys thctailings upward and forward, and they are delivered through the spouts 0 onto the ends of the cylinder G, between the flanges G and sides of the machine for retreatment.

If oats are treated, the main portion of the oats will pass through the hole at the rear end of the screen 7: while the finer oats may pass through the screen It? onto the screen It, this screen being tine enough to prevent the oats from passingonto the seed-riddle. Consequently any oats, whether on the screen k or It, must go to the spout O. \Vhen timothy or clover seed is thrashed, the seed, which passes through all of the screens, falls on the floor k, andis deposited, like othergrain,into the spout 0. All of these different separations are performed without altering the screens and shaking-shoes or shaking-spouts at the rear end of the machine. \Vhen clover is to be separated, the tailings are repeatedly carried forward to the cylinder until the seed is removed from the hull.

In separating wheat and oats it is necessary to use only one of the conveyers J for carrying the tailings back to the cylinder; and in order to use one conveyer a loose board, 0 is placed in one-half of the cross-spout 0 so as to throw thetailingsintooneconveyer-box. Alikeboard, is also employed in like manner in the cross spout O to convey all the separated grain into one boot, 0*, of the elevator-leg; but when it is desired to use both conveyers, the board 0 is dispensed with, and when the elevator and measurer is used on either side of the machine, then the board 0 is changed from one side of the spout to the other, as the case may require.
